A gas generant is provided which decreases toxic components, in particular carbon monoxide and nitrogen oxides, in generated gas to a concentration practical as an air bag system for automobile. n A nitrogen-containing organic compound such as a compound containing amino group or amido group or a tetrazole derivative and a oxygen-containing inorganic oxidizer such as KNO 3 , Sr(NO 3 ) 2 or KClO 4 are essential components. Therewith one or more metal oxides are contained in the mixed catalyst of the gas generant composition. The oxide is selected from manganese dioxide having a specific surface area not less than 50 m 2 /g; copper oxide having a specific surface area not less than 1 m 2 /g; molybdenum oxides such as molybdenum dioxide, molybdenum trioxide, molybdic acid and ammonium molybdate: and copper oxides, cobalt oxides, iron oxides and silver oxides. |
